The aim of this study was to investigate the effect of reconstituted bone xenograft (RBX) on the repair of bone defect in mandibular cyst patients, and observe the biocompatibility between RBX and host. Twenty-eight mandibular cyst patients, including 16 males and 12 females, were enrolled from the Department of Stomatology in the First People's Hospital of Guilin between July 2005 and December 2006. There were 18 cases with inferior mandibular cyst and 10 cases with superior mandibular cyst. They were treated with the RBX implantation into the bone defect sites. All of 28 patients received 12-month follow ups. No obvious systemic reaction was found, and no abnormality was detected by immunology. At months 3-6 postoperatively, RBX degradation and bone substitute occurred in all patients.

Objective To recognize normal sinus rhythm (NSR), ventricular tachycardia (VT) and ventricular fibrillation (VF) from each other accurately and promptly. Methods A nonlinear descriptor based on multi-scale analysis, Hurst index, as a feature to quantify the nonlinear dynamics behavior of the ECG signal, was quoted in this paper. Results The nonlinear technique, Hurst index was examined and evaluated with ECG signals extracted from MIT-BIH Arrhythmia Database, MIT-BIH Malignant Ventricular Ectopy Database, and CU Ventricular Tachyarrhythmia Database under a specific moving-window length. The experiment showed good performance of this nonlinear descriptor. When the window length was 5 s long, the recognition accuracy for each of NSR, VT and VF was 100%. Besides, the computing speed was much faster than the speed obtained with a traditional non-linear technique, the complexity measure algorithm. Conclusion The Hurst index has a strong potential for life-threatening ventricular arrhythmia recognition in clinical applications.

Objective To investigate the expression levels and clinical significance of programmed cell death 1 ligand (PD-L1) and programmed cell death factor-1 (PD-1) in peripheral T-cell lymphoma (PTCL). Methods Immunohistochem?istry was used to detect expression levels of PD-L1 and PD-1 in PTCL (test group, n=51) and benign proliferative lesions of lymph node tissues (control group, n=20). The correlations of PD-L1 and PD-1 expressions with clinical pathological param?eters and prognosis were analyzed between two groups. Results The expression level of PD-L1 was significantly higher in PTCL group than that in control group (74.51%vs 35.00%,χ2=9.662, P<0.05). The positive expression of PD-1 was signifi?cantly higher in PTCL group than that in control group (66.67%vs 25.00%,χ2=10.074, P<0.05). There were significant dif?ferences in PD-L1 and PD-1 expressions between different peripheral lactate dehydrogenase (LDH) levels of PTCL group (P<0.05). After two cycles of CHOP or ECHOP treatments, the response rate (RR) was higher in PD-L1 negative group than that in positive group (84.6%vs 47.4%,χ2=5.478, P<0.05), and RR was higher in PD-1 negative group than that in positive group(82.4%vs 44.1%,χ2=6.755, P<0.05). The median overall survival (OS) time was higher in PD-L1 negative group than that in positive group (29.8 months vs 17.6 months,χ2=4.413, P<0.05) and the median OS time was higher in PD-1 negative group than that in positive group (29.8 months vs 17.6 months,χ2=8.293, P<0.05). Conclusion There are high expression levels of PD-L1 and PD-1 in peripheral T-cell lymphoma, which is closely related with the elevated LDH in peripheral blood, poor response rate and shorter OS. Therefore, the expression levels of PD-L1 and PD-1 can be used as factors of worse effect of chemotherapy and poor prognosis.

With the development of laboratory medicine,more and more biomarkers have been discovered and applied in the diagnosis and treatment of acute myocardial infarction.For patients with suspected myocardial infarction,early diagnosis and timely treatment can save endangered myocardium and reduce fatality rate to a great extent.The proper use of biomarkers is of important value in preventing cardiovascular events and improving prognosis.This paper reviews the recent literature on new biomarkers in diagnosis of acute myocardial infarction,introduces the characteristics of these markers and their clinical diagnostic value.

[Method] Choose 100 cases, under gastroscope report, make statistics of frequency of disease nature elements and location elements, combine the nature and location for common syndromes. [Result] The H pylori-related gastritis has main disease location elements in stomach, esp. the sinuses ventriculi;the disease nature elements mainly concern hot, wet, sputum stasis, deficiency and blood stasis; the common syndromes: hot stomach, sputum and stasis blocking stomach, wet-hot accumulated in stomach, deficient stomach, wet stranding stomach and stasis blocking gastric col aterals. [Conclusion] Over the inconsistent syndromes in clinical H pylori-related gastritis, the microcosmic elements differentiation can further standardize syndromes and guide the treatment.
